TACK FILLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 335,514, dated February2, 1886.

.Application tiled July 29, 1585.

To all whom t may concern.-

Be it known that I, MARTIN V. B. ETHRIDGE,

. a citizen ofthe United States, residing at Boston, in the county ofSuffolk and State ot' Massachusetts, have invented certain new anduseful Improvements in Filling Devices; and I do declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same, reference being had to the accompanying drawings, and tothe letters and iigures of reference marked thereon, which form a partofthis specification.

This invention relates to a device for iilling with tacks thechute-pieces which are used with certain kinds of tack-driving machinesfor automatically supplying the said machines with tacks; and itconsists in a construction and arrangement of parts which will behereinafter specifically set forth and described.

In the annexed drawings, illustrating my invention, Figure l is aperspective of the chute-piece for the tacks. Fig. 2 is a side elevationof the chute filling` device, and Fig. 3 is an end View of the same.

Likeletters designate like parts.

XVith certain kinds of tack-driving machines it is customary to use achute by means of which tacks are conveyed to the driving meehanism.These chutes are ordinarily constructed of the form shown in Fig. 1, anddesignated by the letter F. It will be seen that this chute isconstructed with a channel extending from end to end, which channel isto be lled with a series of tacks. The heads of the tacks will besuspended by and will slide along upon the top of the inclined sidewalls of the channel, and be thus fed into the machine one at a time,according as its predecessor in the series is taken by the drivingmechanism and utilized in accomplishing the-objects of the machine.These chute-pieces are therefore separable and removable from thetack-driving machine, and they maybe taken therefrom whenever desired inorder to be filled with tacks. It becomes,

therefore, a mattei' of great importance how these chutes can be easily,quickly, and properly filled. Hitherto it has, been done generally byhand; but this is a very slow and laborious method. The device hereindescribed is intended therefore to overcome previous dis- Serial No.172,967.

ing the chutes, and it is therefore so constructed that severalchutes'may be filled at one time.

The mechanism of my present invention consists, essentially, of a rotarydrum provided with internal buckets, within which drum the chutes aresituated in an inclined position, the channels opening uppermost toreceive the tacks as they are thrown into them from the rotary drum.

L represents the rotary drum, a'liixed to a shaft which revolves in abearing supported by a standard, as shown in Fig. 2. This shaft carriesat its other end a pulley or band wheel, with which a beltconnection maybe made with any suitable driving-power. Theinterior surl'aee ot' therotary drum is provided with a circular series of buckets, O O, of anyshape and size suitable for holding tacks, and within 7C and outside ofthe drum, or located in any proper position, is arranged a suitableframe, N, upon which the chute-pieces, several in number, if desired,may be placed, preferably in an inclined position, to receive the tacks.This will be seen by reference to Figs. 2 and 3. As the buckets attachedto the inner surface of the drum occupy but comparatively a smallportion of the interior of the drum, enough rooin is left to containmany of the chutes. Now, in order to till with tacks the chutes whichare situated within the drum, the buckets O O are lirst filled withtacks, and then the drum is rapidly rotated. It is evident that as thisrotation proceeds the buck- 8f J ets will be tipped over to such anangle as to empty out the tacks which they contain. These tacks willfall partly upon the chutes and be caught by them, while the rest willfall down into the lower buckets; but those that are 9o caught by thechutes will enter the channels of these chutes point downward, as shownin Fig. 2, for otherwise they would not be stopped and held by thechutes, but would fall down into the buckets. After this rotation of the95 drum has proceeded long enough the channels. of the chutes will beentirely filled, so that they may be taken from the drum for use in themachine proper.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
